| 20090194141 | DRAIN VALVE FOR A DISHWASHER AND ASSOCIATED APPARATUS AND METHOD - A drain valve for a dishwasher and associated apparatus and method are provided. A housing receives fluid through an inlet channel and channels the fluid toward an outlet channel extending from an outlet port defined by the housing. A sealing member is disposed within the housing and is capable of forming a sealing engagement with the outlet port. A cradle member disposed within the housing is configured to receive and partially constrain freedom of movement of the sealing member. The cradle member is movable between a valve closed position, where fluid flow toward the outlet channel urges the sealing member into sealing engagement with the outlet port to close the drain valve, and a valve open position, where fluid flow is allowed between the inlet channel and the outlet channel, through the housing, without the sealing member engaging the outlet port. | 08-06-2009 |

The multi-tiered basin includes a sink member with a false bottom, and a support grid and filter are interposed between the false bottom and a bottom panel of the sink member. The false bottom, support grid, and filter are readily removable from the sink member. The tank is partially filled with the cleaning fluid and a pump and conduit assembly direct a flow of the cleaning fluid to the basin. The cleaning fluid discharged into the basin flows through a drain hole in the false bottom, through the filter and support grid, and then through a drain hole in the bottom panel of the sink member back into the tank for reuse. The cleaning fluid includes, at least, a surfactant that functions to remove organic waste from the parts being washed. The biological component within the cleaning fluid includes nonpathogenic microorganisms that break down the organic waste. ‘The cleaning fluid is not toxic to the microorganisms. The pump and conduit assembly, in addition’ to aiding ‘in the removal of organic waste, functions to aerate the cleaning fluid to maintain a proper environment for the microorganisms A heater, thermostat, and level control assembly function to maintain the cleaning fluid within a certain temperature range so as to aid in the removal of organic waste and maintain a proper environment for the microorganisms | 12-03-2009 |

| 20120118339 | WATER-BEARING DOMESTIC APPLIANCE - A water-bearing domestic appliance, in particular a dishwasher, includes a liquid storage container, in particular a storage container in which washing liquid can be temporarily stored. At least one flow-control element is arranged in a liquid chamber of the storage container to divert and/or to split the washing liquor flowing into the storage container or being discharged from it. | 05-17-2012 |
| 20120167931 | DRAIN HOSE AND WASHER HAVING THE SAME - A drain hose has a simple structure which absorbs vibration of a drain pump, and a washer has the same. The washer includes a main body, a drain pump disposed at the lower portion of the main body, a drain hose to guide wash water pumped by the drain pump to the outside of the main body, and an anti-vibration member formed of a material differing from the drain hose, and including a corrugation part connected between the drain pump and the drain hose and absorbing vibration of the drain pump during drainage of the wash water. | 07-05-2012 |
| 20120180826 | CENTRIFUGAL PUMP - A centrifugal pump has an electric motor, an impeller driven by the motor and a spiral volute. The impeller has an annular base plate and a plurality of vanes arranged on the base plate. The spiral volute has an inlet, an outlet and an impeller chamber in which the impeller is disposed. The inlet extends outwardly from a top wall of the volute. The outlet extends outwardly from a side wall of the volute in the spiral direction of the volute. The spiral volute has a wrap angle between 360 to 460 degrees. A washing apparatus incorporating the centrifugal pump is also provided. | 07-19-2012 |
| 20120192904 | Siphon Break Apparatus Configured To Substantially Prevent A Siphon Effect In A Fluid Conduit Of A Dishwasher And An Associated Method - According to example embodiments, a dishwasher may include a siphon break apparatus configured to substantially prevent a siphon effect in a fluid conduit configured to drain a fluid from the dishwasher. The siphon break apparatus may include a first check valve in fluid communication with the fluid conduit and exposed to a pressure therein and a second check valve in fluid communication with the first check valve. The first and second check valves may be configured to be substantially closed when pressure in the fluid conduit increases as a result of fluid being pumped through the fluid conduit and substantially open when pressure in the fluid conduit decreases as a result of the fluid no longer being pumped through the fluid conduit. Thereby the siphon effect may be substantially prevented. | 08-02-2012 |
